Natural resistance of Bamboo (Bambusa sp.) to marine wood-borers in Goa waters (India)
1993 - IRG/WP 93-10032
The paper deals with the natural durability of Bambusa sp. against the attack of marine wood-borers in Goa waters. Test specimens of this species were completely destroyed within a short period of nine months due to severe attack of borers indicating its very low natural resistance. Wood-borers involved were Martesia striata (Linnaeus), Nausitora hedleyi Schepman and Lyrodus pedicellatus (Quatrefa...

Lignicolous marine fungi from panels of different timbers exposed along Goa coast (India)
1993 - IRG/WP 93-10037
Colonisation by marine fungi on panels of thirty species of Indian timbers, ten species of imported timbers, marine plywood (coated with polyurethane as well as uncoated) and also on panels of five timber species treated with Copper-Chrome-Arsenic (CCA) and Copper-Chrome-Boric (CCB) preservatives, was studied by exposing test blocks in the Mandovi estuary, Goa (West coast of India) for periods ran...

Natural durability of fifty species of Indian timber in Goa waters against marine wood-borers
1989 - IRG/WP 4150
Results of the investigations on the natural durabilitv of fifty species of Indian timber, based on data collected bv exposing test panels at Betim near Panaji (Goa) continuously for a period of 11 months are presented. The study revealed that none of the timber species tested has any natural resistance at this locality and all the panels were completely destroyed within 11 months. Details on the ...

Comparative natural resistance of eighty-two timber species to damage by marine borers at Goa (India)
1996 - IRG/WP 96-10139
Natural bioresistance of eighty-two species of Indian timbers to attack by marine wood-borers has been presented based on data collected from test panels exposed in Goa waters (west coast of India) for periods ranging from five to thirteen months. All the timber species, except Artocarpus gomeziana and Pterocarpus santalinus, were completely destroyed within a short period of three to six months. ...

Destruction of two tropical timbers by marine borers and micro-organisms in Goa waters (India)
1992 - IRG/WP 92-4176
The paper deals with the pattern of microbial attack in relation to marine borer damage of test panels of African rosewood and Brazilian jackwood exposed in Goa waters (Western India) for a period of seven months. The degradation of wood cell walls in both the timber samples occurred due to infestation of soft-rot fungi and tunnelling bacteria. African rosewood, which was severely damaged by tered...

Resistance of six timber species, treated with CCA and CCB, against marine borer attack in Goa waters (India)
1991 - IRG/WP 4166
Panels of Lagerstroemia speciosa, Toona ciliata, Olea dioica, Pinus insignis, Acrocarpus fraxinifolius and Borassus flabellifer, pressure-treated with a 6.6% solution of Copper-Chrome-Arsenic (CCA) and 6% solution of Copper-Chrome-Boric (CCB), were exposed along with untreated controls, in triplicate, in Goa waters to, assess their resistance to damage by marine borers. The control panels were all...

Natural resistance of twenty-five timber species to marine borer attack in Goa waters (India)
1992 - IRG/WP 92-4178
Natural durability of 25 species of Indian timbers has been discussed, based on data collected from test panels exposed in Goa waters (west coast of India. for a period of 7 months. All the timber species, except Cleistanthus collinus, were heavily destroyed within 7 months on account of the combined attack by Martesia striata (Linnaeus) and Lyrodus pedicellatus (Quatrefages). Cleistanthus collinu...

Performance of preservative-treated rubberwood (Hevea brasiliensis) in Goa and Kochi waters (west coast of India).
1997 - IRG/WP 97-20104
Performance of rubberwood (Hevea brasiliensis) against biodeterioration, when pressure-treated with Copper-Chrome-Arsenic (CCA) and Copper-Chrome-Boric (CCB) and exposed in Mandovi estuary (Goa) and in Kochi waters for a period of 32 months and 9 months respectively, has been discussed. The control panels were completely destroyed within a period of 4 to 6 months at both the localities. The resist...
